SPECIFICATION forming part of Letters Patent No. 295,327, dated March18, 1884.

Application filed August 3, 1383. (No model.)

To all whom, it may concern:

Be it known that I, EnwrN L. BARBER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Filters, of which the followingis a My invention relates to that class of" filters used for purifyingwater for drinking and other purposes; and it has for its object toeconomize both space and expense in the production of a filter whichshall be thoroughly efficient in its working and be easily cleaned.

To this end my invention consists in a waterreceptacle provided with.various compartments and passages, as hereinafter described andclaimed, reference being bad to the accompanying drawings, in which--Figure 1 is a side elevation, part in section and Fig. 2 is an invertedplan view of my filter with the bottom removed. Fig. 3 is a horizontalsection at the dotted line in the upper part of Fig. 1.

A represents a common watercooler having the usual annular space, 13, tobe filledwith charcoal or other non-conducting material.

C is the body or main chamber of the cooler, into which the water andice are placed.

D is a slanting partition separating off a lower corner as a pure-waterspace, from which a faucet, F, draws the water. cl represents a hole inthe partition I), for the purpose of rins- Hole d is provided with aplug or screwcap when not in use.

Gis ahole covered with wire-gauze or perforated sheet metal,communieating with a tube, H, which serves as a receptacle for sponge todo the first or coarse filtering.

I is a chamber surrounding tube H, to be filled with charcoal asafilt-er, receiving water from tube H through openings at the sides ofits lower end. From this chamber the water may be conducted through aseries of other chambers, J K L 31 N P, each chamber having filteringmaterial-such as gravel, sand, charcoal, &c.-and each connection?)between' chambers provided witha screen of wire-gauze or somethingsimilar, to prevent the filtering ing chamber E through gauze g,purified ready for use. A less number of filtering-chambers maybeused-as, for instance, the three chamhers I L 1? may be connected andthe other four dispensed with; or even the two chambers I and P may bemade large enough to extend across the bottom of the cooler and beconnected by passages b, as other chambers are shown. Each of thechambers J K L M N P is provided with an opening, 0, which is plugged orcovered with a screw-cap, that may be removed for cleaning and filteringthe chamber.

0 is a space surrounding and between all the filtering-chambers. Thisspace is filled with charcoal, and may connect with the annular space B.It isfilled through a capped opening, f.

B is a space below the filtering-chamber, which is filled with charcoalwhen inverted and covered with the false bottom S, which fits the casesnugly to keep the charcoal in place.

h is a ventilator for the water'space E. The object of this vent is toallow air to enter the pure-water chamber, so that water may be drawntherefrom freely without waiting for its slow passage through thefilters, andthis tube must rise above the high-water level of chamher 0,or water would flow into or out of it. Each of the filtering-chambersbeing in the usual circular form of tin dishes, the device may be verycheaply made, and the number of chambers may by this plan be increasedwithout limit.

The tube H is surrounded by the chamber I, and its end is directlyopposite to the cap 6 of the chamber, so that the sponge may be removedthrough the hole covered by cap e.

What I claim as my invention, and wish to secure by Letters Patent, is

1. A cylindrical water-vessel having a slanting partition extendingfromthe bottom to one side thereof below the top, completely closing thechamber beneath the partition, a venttube in said partition extending tothe top of the vessel, holes in the bottom of each compartment, one ormore chambers to hold filling material connecting said holes, and afaunot entering the inclosed compartment near its bottom, substantiallyas and for the purpose specified.

2. The water-coolerA, the slanting partition D therein, the opening G,and a screen covering it, in combination with the tube H, having sideopenings near its lower end,asponge ing-chambers I J :K L M N P, eachhaving an or other filtering material in said tube, a cham- Opening inits bottom, and a removable cap ber, I, surrounding the tube, filteringmaterial therefor, and means, substantially as specified,
